Yes diffrent corals do suck up more stuff than others. i know.
so starting last night i am mixing my kalk with tap water, lets call it an experiment and see if it has any positive or negitive effects on my tank.

tony, the prob i have is if i raise my cal individually then my alk drops. the exact opposite happens the other way too. i suppose i have to fork out the dollars for a balanced a/b type additive to raise it.
